COMMUNICATION

[Harikoka]

Hiiii… I am working labview-16 for remote application using TCP/IP protocol .which means server & client .I'hd tried by using local network it is working well but when the server & client are in different networks the communication is not establishing and also I used server internet IP in client side and also the same port can anyone  plz tell me the reason why communication is not happening ….thank u...

Try to ping between the two Machines and check whether they are actually communicating.

When programs don't work, it is almost always Hardware or Software (or "Connection-Ware").  @Palanivel suggested a simple test for Hardware/Connection-Ware -- if this seems OK, then it comes down to "Software".  Attach all the relevant LabVIEW code that "doesn't work", so that we can examine, edit, and test it (or we could just guess what mistake you made, but this seems unlikely to be helpful to you ...).

If you can ping the target machine but not communicate over TCP/IP, and you're on different networks, there's a chance there's a firewall between your devices blocking certain ports.  Have you checked for that?  If that turns out to be the case, you can either switch ports if possible or ask someone in IT to unblock your port.
